This lesson covers imaginary numbers. Students learn that the imaginary number "i" is equal to the square root of -1, which means that i^2 is equal to (the square root of -1) squared, which equals -1. Students also learn to simplify imaginary numbers. For example, to simplify the square root of -81, think of it as the square root of -1 times the square root of 81, which simplifies to i times 9, or 9i. To simplify 11/8i, the first step is to get rid of the "i" in the denominator by multiplying both the numerator and the denominator of the fraction by i, to get 11i/8i^2, and remember that i^2 = -1, so we have 11i/8(-1), or 11i/-8, or -11i/8.

For a complete lesson on subtracting mixed numbers go to http://www.yourteacher.com - 1000+ online math lessons featuring a personal math teacher inside every lesson! In this lesson students learn to subtract mixed numbers by first subtracting the fractions then subtracting the whole numbers. For example to subtract 6 1/3 - 4 2/3 first subtract 1/3 � 2/3. However notice that 1/3 � 2/3 equals a negative fraction. In this situation the first fraction 6 1/3 can be rewritten as 5 + 1 1/3 or 5 + 4/3 or 5 4/3. Therefore the original problem 6 1/3 - 4 2/3 can be rewritten as 5 4/3 - 4 2/3. Now subtract the fractions 4/3 � 2/3 to get 2/3 and subtract the whole numbers 5 �4 to get 1. So 5 4/3 - 4 2/3 = 1 2/3. Note that some of the problems in this lesson also require the student to find a common denominator for the fractions. For example 8 5/16 - 1 1/8.
